'ADJUSTABLE METAL INSERT FOB CONCRETE WORK.

Applicationfiled May 4, 1927. SeriaiNo. 188,747.

This invention relates to improvements in ad ustable metal inserts for concrete work.

Buildin s of concrete construction which are to be faced with stones or bricks are usually provided with vertically spaced apart, horizontally extending angle iron shelves to carry portions of the loads of the stones or bricks. I rily fastened to the concrete walls by stationary bolts and are supposed to be ata stone joint level, but as accuratesettings can not be obtained, the shelves are usually either going objections by providing adjustable metal inserts for concrete work which will permit adjustments of the shelves adapted to be carried thereby to the correct stone joint level and eliminating the necessity for chipping or checking the row therebelow to make. a

, wardly in right angularly extending flanges a proper fit.

A further object of the invention is to provide an adjustable metal insert for a shelf which may be initially set in position and then correctly adjusted when the work reaches the proper height, and after being correctly adjusted it maybe anchored in adjusted position to prevent any subsequent movement.

A further obj ectof the invention is to provide an adjustable metal insert of the class described which may be readily used in any form of concrete wall construction. 7

A further object of the invention is to provide an adjustable metal insert of the class described which is of very simple construction, is easily and quickly adjusted, is inexpensive to manufacture, is strong and durable, and is well adapted for the purpose described.

YVith the above and other objects in View the invention consists of the improved ad justable metal insert for concrete work and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a vertical sectional View through a concrete wall showing the use of the improved adjustable metal insert;

These shelves are ordina-' Fig. 2 is an enlarged side elevation of the insert and an angle iron shelf carried there:

by, the'latter being in section; and I Fig; 3 is a sectional view taken on line 33-of Fig. 2. Referring now more particularly to the rows of metal inserts 6.

drawing it will appear that the'numeral 5 indicates a concrete wall in 'which are .em v bedded vertically spaced. apart horizontal As shown clearly in Figs. 2 and 3 eachinsert 6 is formed of a pair of complementary plates 7' having contacting medial portions which are secured together by a rowof rivets r l i 8. lhe plates 7 diverge rearwardly of the contacting-portions and have'angular extremities, forming anchoring portions 9 which prevent the withdrawal of the inserts from the wall. The plates forwardly of the contacting portions are separated,eachhaving a rounded portion 10, forming thercbetween an elongated oval slot 11, and extending from the rounded portions are straight portions 12 forming a slot 13 in communicat on wlth the slot 11. The plates terminate forgle iron shelf 16, positioned adjacent thev outer face of the wall 5, is adapted to be supported by the bolts projecting from two or more of the inserts. As shown, the outer end portion of each bolt extends through an aperture 17 provided therefor. in the vertical flange of the shelf, and a nut 18 threaded 7 onto the bolt holds the shelf thereon.

In building constructions, the metal inserts, together with the angle iron shelves for temporarysettings are placed in the false work ready for the concrete to be poured. When the concrete has been poured the inserts become imbedded therein, but the bolts, supporting the angle iron shelves are free to be adjusted vertically within the slots of the 1 inserts. The stone work is then run up to the proper level and at this point it is desirable to adjust the shelves. This is done by removing the same from the bolts and then resetting the bolts so that the shelf when inserted will be even with the stone joint. The setting of the bolts may be done by leveling a belt at each end of the wall and then adjusting the intermediate bolts to a line drawn between the two end bolts. After this has been done the slotsof the inserts should be filled with cement or mortar to anchor the bolts firmly in adjusted positions and then the shelves are replaced and held by the nuts The stone setter may then continue a row or column of stones 19 upwardly to the next shelf which may be correctly set in the same manner. By this construction, therefore, the shelf may always be adjusted to the stone joint level and the expense and Waste of time incident to checking'a row of stones to fit under a shelf is eliminated.

From the foregoing description it will be seen that the improved adjustable metal inserts for concrete Work are of simple and novel construction, and are well adapted for the purpose described.

- WVhat I claim as my invention is:

1. In a building construction, an insert member rigidly secured in a structural wall, a bolt projecting outwardly from said insert and terminating exteriorly of the wall, the

bolt being only vertically adjustable with respect to the insert, a right angularly shaped shelf carried by the outer end portion of the bolt with its vertical flange immediately adjacent the outer surface of the wall, means for temporarily securing the boltin adjusted aortions of the same the inner end portions l a i ,c

of said plates being formed with angular diverging anchoring portions, a boltverticall'y adjustably positioned within the slotted opening on each insert and projecting laterally therefrom exteriorly of the wall, and.

an angular shelf member secured on the pro ectlng ends of a pair of bolts wlth its vertical flange immediately adjacent the outer surface of said Wall. 7

In testimony whereof,1 allix my slgnature.

CHARLES H. BAUER.
